Once setting assignee to Jeff to ask for help.

Thanks.  You've done the right thing by opting out of LTO for now.  Because you used a standard opt-out my scanner has already flagged mopac7 for deeper analysis -- at first glance I suspect we've dropped a PIC or are mixing PIC and PIE.  THe latter in particular has caused problems in a few packages as we've enabled LTO.  I won't know for sure until I dig into it further.

Given you're using a standard opt-out and thus my scanner has it flagged for deeper analysis and the immediate FTBFS issue is worked around we can close this BZ.
